Patients with risk factors after cervical cancer surgery need radiotherapy, or patients with advanced cervical cancer can also undergo post-mount radiotherapy. Post-mount radiotherapy can increase the local radiation concentration, which has good therapeutic effect and less damage to the surrounding organs and less systemic reaction. However, post-mounted radiotherapy can cause pelvic adhesions and form a frozen pelvis, which can cause slight damage to the vagina or rectum and can lead to vaginal atresia or chronic inflammation of the rectum in the distant future.
